“…Besides, another reason of low BTE with DF can be attributable to higher energy content of DF as compared to that of biodiesel and alcohols. Similar results were also reported in [6,7,17,25,27].…”

Due to the increase in fossil fuel prices, limited reserves and environmental damage, researchers turned to renewable energy sources. Studies have been conducted on the use of biodiesel to reduce the use of fossil fuels used in vehicles. In this study, biodiesel obtained from cottonseed oil by transesterification method was used as fuel. Cotton oil methyl ester and methanol, different proportions of fuels (diesel fuel (DF), 20% biodiesel (BD20) by volume, 20% methanol (AL20) and derivatives (BD20AL20) were obtained. The effects of DF and other fuels on the combustion and performance characteristics were discussed. The tests were conducted on a single-cylinder diesel engine at the varying engine speeds from 1750 to 3250 rpm with the intervals of 500 rpm. In comparison with that of conventional DF, the BSFC value of BD20, BD20AL20, and AL20 test fuels has exhibited a significant increment with 10.4%, 39%, and 24%, respectively. DF has the highest value with 28.93% BTE. The reason of the high BTE for DF is the heating value, and high-energy content thereof. In comparison with that of DF, the BTE value of BD20, BD20AL20, and AL20 test fuels has exhibited a significant decrease with 6.8%, 16.74% and 9.5%, respectively. Maximum in-cylinder pressure and maximum heat release rate values are observed for the test fuels containing biofuels due to their low cetane number as compared to that of DF.

“…At elevated load conditions, the fuels can enter at proper condition to ignite to produce improved combustion efficiency. e similar pattern of output was also obtained from the previous researchers [36,37]. In comparison to diesel fuel, the increment on the BSFC value is calculated to 3.85, 7.69, 19.23, and 26.92% for B5, B10, B15, and B20, respectively.…”

Plastic is a resilient, chemically inert, lightweight, and low-cost material. It sticks around in the environment for more than hundred years, threatening nature and spreading toxins. The current study deals with the use of waste polymeric materials and de oiled cake for the production of liquid oil and its blend on the performance and emission characteristics of diesel engine. The tests were conducted in an engine fuelled with diesel and four distinct blends such as 5% (B5), 10% (B10), 15% (B15), and 20% (B20), respectively. The liquid oil was produced by co-pyrolysis of neem de oiled cake (NDC) and waste polystyrene (WPS) in 1 : 2 blend ratio. The raw pyrolysis oil and its different blends were tested for their physical and chemical characteristics in order to find their suitability. Brake power (BP), brake thermal efficiency (BTE), brake-specific fuel consumption (BSFC), emissions of carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) are used to assess the performance of the engine. The experimental results reveal that BTE at all blends is lower than diesel at all loads and the BSFC increases with increasing blend ratio and falls with increasing engine load. At higher loads, the deviation of performance and emission values from baseline diesel up to B10 is very small. It is found from the results that the liquid oil derived from NDC and WPS up to 10% blend will be the promising additive for fossil fuels.

In present scenario, the fast depletion of fossil fuels and energy crises motivated the researchers towards finding an alternative sources for energy. In this work, the performance, combustion and emission of hydrothermally synthesized ZnO nanoparticles dispersed waste cooking oil biodiesel in single cylinder, four stroke, Direct Injection- Diesel Engine with eddy current dynamometer was investigated. The synthesized ZnO nano particles were characterized by XRD, FTIR, SEM and EDX to find crystallinity, functional groups and surface morphology. Waste cooking oil biodiesel was produced via conventional one step alkali catalyst Trans-esterification process. Test fuels were prepared with dispersion of ZnO nanoparticles in the concentration of 10ppm, 20ppm and 30ppm with B20 (20% waste cooking oil biodiesel and 80% diesel) with the aid of magnetic stirrer and ultra-sonication. The test results exposed that the addition of ZnO nanoparticles with B20 gave better Performance in terms of BTE and BSFC compared to B20. The addition of ZnO nano particles with 30ppm concentration was identified as better fuel among all tested fuels in this work. 30ppm addition of ZnO nano particles with B20 records 1.78 % increase in BTE and 10.34% decrease in BSFC. The emission like CO, HC and smoke were 20%, 15.4% and 17.39% lower than diesel. On the other hand NOx was slightly higher than diesel but lower than B20.
